Since 2009, in the aftermath of Sri Lanka's ethnic war, certain contingents of Sinhala Buddhists have lodged attacks against religious minorities, whom they censure for committing violence against animals in accordance with the dictates of their gods. Considering these interventions against sacrifice in spaces of shared Hindu and Buddhist religiosity, this article examines the economies of derogation, violence, and scapegoating in post-war Sri Lanka. Within Sinhala Buddhism, sacrifice is considered bio-morally impure yet politically efficacious, whereas meritorious Buddhist discipleship is sacrificial only in aspirational, bloodless terms. Nevertheless, both practices fall within the spectrum of Sinhala Buddhist religious life. Majoritarian imperatives concerning post-war blood impinge upon marginal sites of shared religiosity—spaces where the blood of animals is spilled and, ironically, where political potency can be substantively shored up. The article examines the siting of sacrifice and the purifying majoritarian interventions against it, as Buddhists strive to assert sovereignty over religious others.
